Hi, it’s a Ladies Pocket watch converted so it can be worn as a pendant.
Tiffany (like other stores of the time) didn’t manufacture watch movements, they bought those from Swiss watchmakers ie Longines. They made the watch cases and retailed them with their “stores” name on the watch face.
The winder is a replacement or the original one cut down (no loop on winder) - you can see where the winder inserts into the case that the “hole”isn’t a proper fit.
The pendant section with bale for wearing on a necklace has been added.
Value?
Ladies pocketwatches sadly aren’t particularly collectible or desirable these days and the alteration to the watch (conversion to a pendant style) does affect its value to those who seek original pieces. The engraving in the case is also a negative impact on value, unless they match the buyers! You could possibly see if the monogram can be buffed off by a jeweller.
Does it run? Does it keep time (1 or 2 minutes slow or fast in a 24 hour period is to be expected.
It’s value will be based on whether it works and gold weight / value. I don’t recommend you trying to get the movement out, leave that to a watchmaker. You could assume the movement weighs 4 or so grams so that’s say 9 grams net. Current melt would be around $300.
So if the watch isn’t working around $400 if working and keeping time $600 / $800. Hope this helps.

Congrats on the auction win!

That’s a very nice movement on the inside. Adjusted to three positions and it looks to be very clean on the inside. The 11.62N was introduced by Longines in 1909 however the serial number on the movement would date the movement as being produced between 1917-1918. This movement was used in a number of watches for men and women (both wrist and pocket/pendant).

This is from the days when Longines truly was a manufacture d’horologerie until the quartz crisis when they were taken over by what is now Swatch Group. Since then, they have primarily been a caser of slightly modified ETA mechanical and quartz calibers (only until recently when they have worked with ETA on developing specialist calibers that are only found in Longines models).

Agree with @Bron357 that the crown is not original and would likely have been something that a watchmaker added during a service of the movement. Here’s hoping that the movement still runs.

The case is likely to be worth more than anything else due to melt value, but assuming that the dial and hands are original, this would add to the charm of the piece. I actually love the Breguet hands (potentially heat blued as opposed to painted) and numerals on the dial. Reminds me a lot of what Tissot did in 2016 with their Heritage 1936 timepiece (which essentially was a pocket watch movement in a wristwatch case).

Just trying to get a sense of what is on offer at places like Chrono24, and there are some crazy prices that people are asking for them.

Over at a watch forum I frequent, someone asked a similar question about a Tiffany pocket watch with the same Longines calibre in it and of a similar vintage, in June 2018. The interesting thing was that their pocket watch had a similar Breguet dial but also included a small seconds counter at 6 o'clock which your piece does not have.

If you wish to obtain further information about this watch from Longines, you can do so by following the instructions at the following link:

While the certificate of authenticity costs money, you can get a free "Extract from the Archives" sent to you on official Longines paper that provides more information about the movement and timepiece.
